Abstract
PURPOSE: To prepare a homogeneous and transparent solution of acrylonitrile polymer having a high molecular weight, by extruding the polymer solution prepared by polymerizing the mixture of acrylonitrile monomer with a mixed solvent composed of water and DMF or DMA, together with heated DMF or DMA by means of a vented screw extruder.
